Subject: [PATCH gnumach 2/3] vm: allocate a large map for all objects larger
 than SMALL_SIZE

* vm/vm_external.c (vm_external_create): Allocate a large map for all
objects larger than SMALL_SIZE.  'vm_external_state_{g,s}et' can deal
with offsets larger than 'LARGE_SIZE', so currently objects larger
than 'LARGE_SIZE' are missing out on the optimization.
